Interesting acoustics

Post by Michael L » Sun Aug 12, 2018 12:47 pm

I walk the dog under a viaduct which carries trains over the River Severn in Shrewsbury.
I enjoy the reverberation in the arch we pass through and thought I would record some foot stamping.
Perhaps others have their own favourite places with interesting acoustics.



The longest reverbs seem to occur when triggered about a quarter of the way in. I've no doubt there's a formula.

I have to say, if viewed out of context, that's a really surreal video :D

Yes you're right Mike!
I've always been fascinated by sound. I loved my PE Minisonic synth that I built as a teen despite the fact that it couldn't hold pitch for any time. As a BT apprentice I spent a couple of weeks in the tunnels under Newhall St in Brum. They were very good for echoes and reverb fun. I only lasted two weeks mind - due to my SAD. I needed light and pleaded to be able to cut short my assignment. It used to be hush hush down there until a Lord Mayor unwittingly discussed the place in a speech.

...I was waiting for the drums to start and the bass kick in.

I thought it was the start of a trippy dub track!

The effect is rather lost in the recording sadly. It's a massive structure and the sound reflecting back and forth end to end is very impressive. I wonder why it dies off so suddenly after five or six reflections. You may think I need to get out more but I was! It's the sort of sound that totally ruins concerts of course. I remember seeing Dweezle Zappa and band at Birmingham Town Hall - sadly not a structure built for amplified music - terrible sound. We had seen him at Warwick Arts Centre a couple of years before. May have well been two different bands such was the difference in acoustics.
